Teknetics G2 - Not G2 Plus+

[marlee]

Hello Metal detectors.

I have a Teknetics G2 it is an old grand ma but it had her success.

i tried to turn it on today and i did not get any signal on the screen.

and when trying to move the disk to test it all of sudden it starts beeping and it gives me a blinking message Saying overload as you can see in the modified photo.

i was hoping that one of you has faced the same problem or has an idea about this Error i call it, and if it is fixable.

Thank you.

Were you swinging the coil over a big piece of iron?

no i was not.
the machine was working fine and after a few days i started it to test a place and only then the overload happend as soon as i started the machine.

i dont have a spare disk or cable to test them it is hard to obtain this kind of equipments where i live so fixing it is my only option.

Unplug the coil, turn it on, see if it overloads. If it does, something in the circuit is messed up. If it does not, something in the coil is messed up.

Edit: with the coil unplugged and unit turned on and not overloading, lick the tip of your index finger and stick it in the connector on the back of the pod so that you touch the various pins. You should get the detector to respond with random beeps & IDs which would indicate it's working. I'm guessing the coil has a short in it, probably in the connector housing.

what you saying fits the problem. when i touch the pins i get random noises wich indicate the unit works fine and i get no overload message when i unplug the disk however the disk it self is working and has no problem.

i think the problem is in the socket that goes into the unit. because zhen i forcely bend the cabel at the end i can make the overload message goes away and i get unstable beeps when i put a metal target in front of the disk i get signals (but not stable because the connection) so i think the disk is fine.

is it easy to open the socket and try to fix the cables inside ? i dont want to ruin the connection because i wont be able to get a spare part.

i went by ur advise and dismantled the connector.
it turns out it was freak up from inside the cables where disconnected and turned around each other.
i was surprised that could happen after organizing them and soldering them properly the random noise is n longer along the overload message. now i work as good as new and there is no stress on the signal.
thank you so much for sharing your opinion with me it really helped.

Nicely done, but now it sounds like a child screaming. You sure you fixed it?

i mean a child screaming that still detectes metals is better than a detector thats not working hahahahha

but if there is anything else you think i could do i would be happy to try it out.
